I'm drinking my first batch of this at the moment. I undershot my expected efficiency by quite a bit, so I ended up with an OG of only 1.052. It finished a little lower also - 1.014. Despite being slightly thin, it still tastes pretty good! I'm only getting a hint of the Citra hop aroma, despite doing the 7-day dryhop. It's been in bottles for almost three weeks now.
Would a thin mash impact hop aromas at all? I'm leaning toward either that, or the fact that I strained all the hops out of the wort before chilling after boil, as being the culprit for not being quite hoppy enough.
I have a second batch of this about to be dryhopped. I also undershot my expected efficiency on that one, but left the hops in the kettle while chilling the wort. It will be interesting to see if I notice a difference.
